Asus B150 Pro gaming Aura Bios Blackscreen

My buddy has a Asus B150 Pro gaming Aura board did the bios update to 3805 and now he gets nothing but a black screen what can we do to re install old bios. Tried removing cmos battery nothing tried ctlr+home while powering up also tried holding escape and hitting f5 then down then enter. all USB devices are not powering on boot as well, also tried using HDMI on mobo video out instead of GPU nothing.

Edit* Found these going to order one and see if it fix’s it
